Oh, you're one of "those" (g,d&r!).
But on all the SBCs and 'vairs I've had to work with, I've never adusted the valves with it running. There's simply no need. The idea is to center the hydraulic lifters' plungers in the center of their travel, and you can easily do this with the engine off, by hand rotating the engine to the base circle of the cam lobe, loosen the adjuster to get the least amount of lash discernable, then preload to spec (3/4, 1, 1.5, whatever).
Well, whatever works. Certainly, you can adjust SBC hydraulic lifters with the engine running. It's completely unnecessary, but it's the sort of procedure that's ingrained in the culture, so that's that. I've even seen one repair manual describe how to do it. Sheesh.
Unfortunately, we now live in an age where disinformation is disseminated as fast as information, and the real skill lay in determining which is which.
Pardon my ignorance, but what is "g,d&r"?
Pre-load for sbc is .400".......I know that. I have built several of them in the last 15 years and all are still running.................
If I appear to be "ignorant" or "inexperienced", then I am not coming across clearly here.
Misinformed? Maybe, but old habits die hard. I only came here to learn how to keep my car on the road. It's that simple. Actually, I hate working on cars in general (just tired of it) and avoid it at all costs. I don't think we need to be "professional" mechanics or belong to SAE to work on or maintain these cars.
I still think the oiling system on the EA82 is a strange animal and requires clean oil........or else!!..............The curse of the loud lifters will be upon us........
Glad to hear your car is running well............
Hope you enjoyed the holiday weekend.
